A new casino can later become to scam. Sometimes the people that created the casino may not be able to market the casino very well and because of low profit in a way the casino can no longer function, they just stop the casino and not allowing people to withdraw.
I too will advice people to just try the casinos or other gambling sites on this forum instead. If it is a new casino, they should try it with little amount of money. They should try the ones that have signature campaign which are able to market their gambling sites on this forum. The gambling sites that I have gone for on this forum have active signature campaign and also having active announcement thread.
If it is a new gambling site that is not in this forum, I do not try to register and this has been the reason no casino has scammed me before. I am not saying that new gambling sites can not scam, use very low amount of money to gamble on such gambling sites.
Obviously, it just about moderate risk taking trying the site with small amount of money, bet and withdraw to your bank account if they actually process withdrawal as claimed, sometimes you won't really tell a possible scammer betting platform, some act as wolfs in a sheep clothing, everything will seem good at the beginning but when they must have gotten a number of clients to scam, they go thin air.
Risking an amount you can afford to lose is just key to surviving in the online digital space.
Basically, not everyone can know about which casinos have the potential to cheat their members or which casinos are truly proven safe, especially for beginners who have just entered gambling, but one thing as you said that the only way is to keep ourselves on the right path, in the sense of having an approach full of prevention so that something unwanted does not happen to you too significantly.
Betting with only a small amount is the best action and I also always do it especially when trying a new casino, but of course in the long run it is also always the recommended approach, the point is to be careful because in most cases what is usually the enemy of gamblers is their own emotions.
